Energy-plus building

An energy-plus building is a type of building that produces more energy than it uses. It does this by using energy-efficient materials and systems. The energy-efficient materials help to reduce the amount of energy needed to heat, cool and light the building. The energy-efficient systems use energy sources like solar and wind to generate energy and make the building more energy-efficient. By producing more energy than it uses, an energy-plus building is better for the environment and saves money in the long run.
